Here's a combined review and installation of Knoppix on old hardware – a Celeron 333 MHz processor, with 96 MB SDRAM.
The conclusion is clear:Quote:

Advantages of Knoppix

* Multimedia programs compiled with MP3 support. * Auto detects a wide variety of hardware including certain off-beat ISA cards. * Contains a lot of softwares, which usually have to be downloaded separately and installed in other distributions. * Knoppix is based on Debian so can easily update, install or upgrade using Apt package management. * Coexists with other OSes with out any problem via the GRUB boot-loader. * Sound configuration is automatic and is not a hassle. * If the hardware is atleast 4 years old, then knoppix is a viable choice of installing and using Linux. * Appeals to people without broadband internet who want to install a more complete Linux with support for many proprietary file formats like MP3. * Contains multiple window managers like KDE, Fluxbox, IceWm, twm etc.

Disadvantages of Knoppix

* Knoppix is optimized for use as a live distro. So when installed on the hard-disk will boot up a bit slower than other distributions. * If you want to learn the inner working of Linux, this is not the best way. You will be better off installing a distribution like Slackware, Fedora or Ubuntu.
